Capacity and form factor

This is a single 4 GB DDR4 DIMM running at 2133 MHz with a PC4-17000 rating. The module uses the standard 288-pin desktop layout and operates at 1.20 V without ECC or registered buffering.

Desktop users needing a direct replacement

It suits owners of systems that accept unbuffered non-ECC DDR4 at this speed and voltage. Buyers whose boards require ECC, registered modules, a different DDR generation or a higher density per slot should look elsewhere.

Verified compatibility with the Hynix part

The stick is tested as a drop-in substitute for the Hynix HMA851U6AFR6N-TF module. That validation means the upgrade installs without configuration changes and restores the original memory capacity and timing profile.

Questions about this item

My motherboard has four 288-pin DDR4 slots and currently runs a single 2133 MHz stick — will this 4 GB module work alongside it?

Yes, this unbuffered non-ECC DDR4 DIMM matches the 2133 MHz PC4-17000 speed and 1.2 V voltage, so it will run at the same frequency and timings as your existing module when installed in a free slot.

After installing the module, how can I confirm the system sees the full 4 GB at 2133 MHz?

Open Task Manager Performance tab or run CPU-Z; both will show 4 GB capacity, DDR4 type, 2133 MHz speed and 1.2 V voltage for the new stick.
